Could it be?!?!

Jada

My husband and I have been TTC for some time now with <a href="https://glowing.com/glow-fertility-program">IUI</a> for our third baby. I triggered on 1/12/19 then tested out my trigger shot, it was gone by day 9. I took a test this morning and saw a very faint line, I took 3 more at lunch of FRER and got positives, took one more this evening positive again. I’m supposed to test this Saturday the 26th to find out 100%. What do you all think? Could it really be, OR could this be my trigger shot lingering?
